Abstract
A good outreach project must have an educational aspect that includes experiments in an inquiry based teaching methodology, enabling students to exploit the full potential of the project. The CESAR telescope network is an excellent educational tool that provides a comprehensive set of activities to students, such as the study of Jupiter's magnetosphere or the origin of the emission from radio sources, using radio telescopes; the discovery and follow-up observations of extrasolar planets or supernovae, using optical telescopes; and the study of the solar dynamics and activity using solar telescopes.
